Historical Reference

Developed in 1941 through 1942 on the basis of the M5 Stuart light tank. This SPG is an example of the successful use of an outdated chassis. The vehicle was equipped with a 75 mm short-barrel howitzer; however, attempts were made to fit a 75 mm tank gun into a modernized turret.
